Hypermiling Wiki Knows Fuel Economy
Yes, wiki.com has a few pages devoted to hypermiling and hypermilers - and for good reason - fuel economy.
Fuel economy-maximizing driver behavior adjustments using techniques used to optimize auto or motorbike fuel economy. The driver really can influence engine efficiency, aerodynamic drag, rolling friction and kinetic energy lost to braking and absent regenerative braking.
You probably know that that city mileage is lower than highway because of more idling, operating at inefficient low-output engine operating points and more frequent braking.
Some basic fuel economizing techniques include maintenance of your vehicle such as: 1. High tire pressure 2. Tire balance and alignment 3. Engine oil with low kinematic viscosity (low-weight motor oil) Inflating tires to the maximum air pressure is important as under inflated ties can lower fuel efficiency by 1.4% for every 1 psi drop in pressure of all four tires. Not to be overlooked is proper care of the engine control module and its sensors that control engine operation, particularly the oxygen sensor. Drivers can also increase fuel economy by simply driving lighter-weight vehicles and not carrying a great deal of luggage, tools, and equipment. Fuel Efficient Speeds Maintaining stable speed is an important factor too. Best efficiency can be expected while cruising without frequent braking, at minimal throttle and with the transmission in highest gear. Obviously optimal speed varies per make of vehicle but it's safe to say that speeds between 35 and 55 mph seem to give the best economy. Braking Habits
Generally acceleration is most efficient at 75% to 100% throttle openings, but accelerating too quickly without being observant of what's ahead may require braking and of course additional acceleration. Since braking is often unpredictable the driver may have to slow or stop the vehicle at a fixed distance ahead. Traveling at higher speeds results in less time available to let up on the accelerator and coast. At medium speeds, the driver has more freedom of decision and can elect to accelerate, coast or decelerate depending on whichever is expected to maximize overall fuel economy. For example, when approaching a red light drivers may opt to time it by easing off the throttle or braking if necessary far before the signal. Instead of coasting up to the light and stopping the driver could travel at a slower speed for a longer time allowing the light to change to green before arrival. So fully stopping isn't necessary.
